摘要：

Using an exchange reaction involving one PCy3 ligand in HRu(CO)CL(PCy3)(2) (1) for one IMes, a ruthenium-hydride complex HRu(CO)Cl(PCy3)(IMes) (2) has been, prepared. Complex: 2 is an active catalyst in the hydrogenation of alkenes. A TON of 24 000 h(-1) has been obtained at 100 degreesC under 4 atm of hydrogen. Addition of HBF4. OEt2 as cocatalyst enhanced the catalytic activity.
